Description of a neiv genus of Land Shells from the Island

Plcctostoma De Crespignii, H. Adams. 



" It appears to liave affinities with the genus Boysia, Pf., 

 and Hypselostoma, Bens., from which, however, it diiTers in 

 having the last whorl constricted at its separation from the 

 others, and in the extraordinary prolongation backwards of 

 the free portion. From Boysia it also difiers in being more 

 heliciform, and in having the umbilicus open ; and from 

 Hypselostoma in the aperture being edentulate."
